KEY MESSAGES

- Unseasonably mild weather continues through Tuesday, with near to slightly below normal temperatures returning by the end of the week.

- A quick-hitting system will bring rain chances to some on Wednesday, with light accumulations. Otherwise, largely dry conditions will be seen through the upcoming weekend.

SHORT TERM /THROUGH TUESDAY/

Issued at 1249 PM CST Mon Nov 9 2026

High pressure will remain situated southeast of the area, which will help direct llvl southwesterly flow into the region. This will continue to favor above normal temperatures throughout, with most seeing temperatures in the low 60s and mostly clear skies this afternoon. Tonight, a weak wave will pass through which will disrupt our warm advection briefly. Although, we will see increasing heights through the first half of Tuesday as weak ridging and a surface high passes overhead. As this high pressure passes east of the area Tuesday afternoon and evening, llvl winds will increase out of the southwest, favoring some warm advection into the region. Once again, we will see another pleasant day Tuesday, with above normal temperatures and mostly clear skies. Although, temperatures may be a few degrees cooler than Monday, owing to cool advection through the first half of the day.

LONG TERM /TUESDAY NIGHT THROUGH MONDAY/

Issued at 1249 PM CST Mon Nov 9 2026

Tuesday Night into Wednesday, we continue to watch a wave track southeast through the Central CONUS, bringing increasing cloud cover and precipitation chances to the area. Confidence on rainfall remains low-medium, owing to uncertainty amongst guidance on moisture availability. Soundings would favor the potential for light rainfall, but saturation may take some time. We continue to see widespread 30-50% PoPs through the day, with best chances in the afternoon east of the Mississippi River. While the chances may be more widespread, we are not expecting widespread heavy rainfall. Most locations may get through the day without seeing much, if any, rainfall. Rainfall accumulation is expected to be lower as well, where those that see rain can expect light accumulations <0.10". Otherwise, a mostly cloudy day can be expected with temperatures in the mid-upper 50s.

Wednesday Night-Sunday, another shortwave to drop south in the northwest flow aloft on Thursday. Guidance has trended down on the rainfall potential compared to the last forecast package, leading to little/no PoPs. If we manage to see any precipitation, it will likely be isolated showers passing through the cyclonic flow over the region, but that is low confidence. What is of higher confidence, is the colder air arriving behind this wave. High temperatures to drop closer if not a few degrees cooler than normal into the low 40s Thursday and Friday, especially if clouds stick around longer. After Friday, a large area of high pressure and a building upper ridge over the central CONUS will bring another period of dry conditions and above normal temperatures.

AVIATION /06Z TAFS THROUGH 06Z WEDNESDAY/

Issued at 1130 PM CST Mon Nov 9 2026

Another VFR TAF cycle through Tuesday as a frontal passage taking place now incoming from the northwest lingering into early Tue morning, is followed by a ridge of high pressure. Generally a light sfc wind regime with wind veering to the northwest or north into Tue morning, then trending light and variable by late Tue afternoon. Just streaks of cirrus for any type of cloud cover in the ongoing dry air mass.
